Yet another embodiment of the present disclosure can entail a network device comprising a controller programmed to store a subscriber selectable preference for advertisements used for selecting advertisements to send to a set top box (STB) and receive a signal from a broadcast stream indicating the location for insertion of an advertisement based on the subscriber selectable preference.

FIG. 1 depicts an illustrative embodiment of a first communication system 100 for delivering media content. The communication system 100 can represent an Internet Protocol Television (IPTV) broadcast media system. The IPTV media system can include a super head-end office (SHO) 110 with at least one super headend office server (SHS) 111 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent audio content, moving image content such as videos, still image content, or combinations thereof. The SHS server 111 can forward packets associated with the media content to video head-end servers (VHS) 114 via a network of video head-end offices (VHO) 112 according to a common multicast communication protocol.

The VHS 114 can distribute multimedia broadcast programs via an access network 118 to commercial and/or residential buildings 102 housing a gateway 104 (such as a common residential or commercial gateway). The building 102 can be various types including multi-dwelling units which house a plurality of different subscribers. The access network 118 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over optical links or copper twisted pairs 119 to buildings 102. The gateway 104 can use common communication technology to distribute broadcast signals to media processors 106 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 108 such as computers or television sets managed in some instances by a media controller 107 (such as an infrared or RF remote control).

The gateway 104, the media processors 106, and media devices 108 can utilize tethered interface technologies (such as coaxial or phone line wiring) or can operate over a common wireless access protocol. With these interfaces, unicast communications can be invoked between the media processors 106 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.

Some of the network elements of the IPTV media system can be coupled to one or more computing devices 130 a portion of which can operate as a web server for providing portal services over an Internet Service Provider (ISP) network 132 to wireline media devices 108 or wireless communication devices 116 by way of a wireless access base station 117 operating according to common wireless access protocols such as Wireless Fidelity (WiFi), or cellular communication technologies (such as GSM, CDMA, UMTS, WiMAX, Software Defined Radio or SDR, and so on).

Another distinct portion of the computing devices 130 can function as a server (herein referred to as server 130). The server 130 can use common computing and communication technology to perform the function of relaying and/or receiving media content to ISP network 132 or to other networks.

It will be appreciated by an artisan of ordinary skill in the art that a satellite broadcast television system can be used in place of the IPTV media system. In this embodiment, signals transmitted by a satellite 115 supplying media content can be intercepted by a common satellite dish receiver 131 coupled to the building 102. Modulated signals intercepted by the satellite dish receiver 131 can be submitted to the media processors 106 for generating broadcast channels which can be presented at the media devices 108. The media processors 106 can be equipped with a broadband port to the ISP network 132 to enable infrastructure services such as VoD and EPG described above.

In yet another embodiment, an analog or digital broadcast distribution system such as cable TV system 133 can be used in place of the IPTV media system described above. In this embodiment the cable TV system 133 can provide Internet, telephony, and interactive media services.

In one embodiment, the building 102 can have a surveillance system 150 including various security devices such as security cameras, motion detectors, automated door locks, intercoms, processors and so forth. Each of the units and/or subscribers within the building 102 can have a cognitive radio transceiver (CRT) 175 that can wirelessly receive signals from the surveillance system 150. The signals can be video media captured by security cameras throughout the building (such as at the front door, the pool, and so forth).

FIG. 2 depicts an illustrative embodiment of a portal 202 which can operate from the computing devices 130 described earlier of communication system 100 illustrated in FIG. 1. The portal 202 can be used for managing services of communication system 100. The portal 202 can be accessed by a Uniform Resource Locator (URL) with a common Internet browser such as Microsoft's Internet Explorer™ using an Internet-capable communication device such as those described for FIG. 1. The portal 202 can be configured, for example, to access a media processor 106 and services managed thereby such as a Digital Video Recorder (DVR), a VoD catalog, an EPG, a personal catalog (such as personal videos, pictures, audio recordings, etc.) stored in the media processor, provisioning IMS services, provisioning Internet services, provisioning cellular phone services, provisioning services such as security services or advertising services and so on. For example, a user can utilize the portal to configure the cognitive radio processor for receiving video security footage as it is captured by security cameras in the building. In another embodiment, the captured video can be forwarded to other communication devices and/or entities, such as a mobile telephone of the user or the police. In yet another embodiment, the services can enable the insertion of targeted advertising as set up by the subscriber or other entity.

FIG. 3 depicts an exemplary embodiment of a communication device 300. Communication device 300 can serve in whole or in part as an illustrative embodiment of the communication devices of FIG. 1. The communication device 300 can comprise a wireline and/or wireless transceiver 302 (herein transceiver 302), a user interface (UI) 304, a power supply 314, a location receiver 316, and a controller 306 for managing operations thereof. The transceiver 302 can support short-range or long-range wireless access technologies such as Bluetooth, WiFi, Digital Enhanced Cordless Telecommunications (DECT), or cellular communication technologies, just to mention a few. Cellular technologies can include, for example, CDMA-1X, UMTS/HSDPA, GSM/GPRS, TDMA/EDGE, EV/DO, WiMAX, SDR, and next generation cellular wireless communication technologies as they arise. The transceiver 302 can also be adapted to support circuit-switched wireline access technologies (such as PSTN), packet-switched wireline access technologies (such as TCPIP, VoIP, etc.), and combinations thereof.

The UI 304 can include a depressible or touch-sensitive keypad 308 with a navigation mechanism such as a roller ball, joystick, mouse, or navigation disk for manipulating operations of the communication device 300. The keypad 308 can be an integral part of a housing assembly of the communication device 300 or an independent device operably coupled thereto by a tethered wireline interface (such as a USB cable) or a wireless interface supporting for example Bluetooth. The keypad 308 can represent a numeric dialing keypad commonly used by phones, and/or a Qwerty keypad with alphanumeric keys. The UI 304 can further include a display 310 such as monochrome or color LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode) or other suitable display technology for conveying images to an end user of the communication device 300. In an embodiment where the display 310 is touch-sensitive, a portion or all of the keypad 308 can be presented by way of the display.

The UI 304 can also include an audio system 312 that utilizes common audio technology for conveying low volume audio (such as audio heard only in the proximity of a human ear) and high volume audio (such as speakerphone for hands free operation). The audio system 312 can further include a microphone for receiving audible signals of an end user. The audio system 312 can also be used for voice recognition applications. The UI 304 can further include an image sensor 313 such as a charged coupled device (CCD) camera for capturing still or moving images.

The power supply 314 can utilize common power management technologies such as replaceable and rechargeable batteries, supply regulation technologies, and charging system technologies for supplying energy to the components of the communication device 300 to facilitate long-range or short-range portable applications. The location receiver 316 can utilize common location technology such as a global positioning system (GPS) receiver for identifying a location of the communication device 300 based on signals generated by a constellation of GPS satellites, thereby facilitating common location services such as navigation.

The communication device 300 can use the transceiver 302 to also determine a proximity to a cellular, WiFi or Bluetooth access point by common power sensing techniques such as utilizing a received signal strength indicator (RSSI) and/or a signal time of arrival (TOA) or time of flight (TOF). The controller 306 can utilize computing technologies such as a microprocessor, a digital signal processor (DSP), and/or a video processor with associated storage memory such a Flash, ROM, RAM, SRAM, DRAM or other storage technologies.

The communication device 300 can be adapted to perform the functions of the media processor 106, the media devices 108, or the portable communication devices 116 of FIG. 1. It will be appreciated that the communication device 300 can also represent other common devices that can operate in communication system 100 of FIG. 1 such as a gaming console and a media player.

FIGS. 4 and 5 depict illustrative embodiments of a system or flow 400 and another system or flow 500 for enabling a subscriber to select and receive subscriber selectable advertising. In this regard, a subscriber can select preferences or even actual individual ad content that can be streamed to the user in a targeted fashion in a digital television system such as an IPTV system. The systems 400 or 500 can provide la carte IPTV Advertising that enable system subscribers to choose advertisements that fit their interests from a Set top Box (STB). The viewer or subscriber can select specific advertising content via GUI (Graphical User Interface) which will in turn store their choices on an Ad Delivery Server. The Ad Delivery Server can then present the subscriber's preferred advertising content during a next available ad break as further detailed below.

Referring again to FIG. 4, the system or flow 400 in one embodiment can enable a subscriber to select ad content from a catalog server using a STB at 402. A billing server can optionally log the subscriber ad content selection at 404. The system can use broadcaster que tone information to determine a location or time (or time slot) for delivery of the ad to a particular subscriber or STB at 406. In one particular embodiment, an Ad Campaign Manager can deliver the subscriber selected ad content (or content in accordance with a selected subscriber preference) to the STB via a unicast transmission at 408.

Such a system can resolve several issues that allegedly disturb advertisers and subscribers. Advertisers would obviously want to discourage channel flipping away from the specific broadcasted content and subscribers are more likely to stay on a particular channel if they had the ability to insert advertisement into the Setup Top Box that pique the specific subscriber's interests. For example as a 40 year old male consumer would not necessarily want to receive product information or services that are only designed for females or receive product information for specific age groups when it is not applicable to them. In this regard, advertising that is not related to the viewer or subscriber's interest may not be as effective as subscriber selected advertising. The consumer will be able to select content from a GUI that is specific to content that personally interests them. For example, sports, sporting events, local events, medical, personal care, environment, travel, automobiles, racing, gaming, fashion or any other particular interest. Other techniques or inputs can be used in addition to the subscriber selectable preference to further refine the particular ads that can be delivered to the subscriber. Other inputs can include, but are not limited to demographics, geographic location, purchase histories and the like. These techniques bring e-commerce to a next level by allowing consumers to be more interactive when purchasing products and services through such a system.

In yet another embodiment, a system or flow 500 can enable a subscriber to request ad content (or ad preferences) via an STB at 502 from an ad server catalog 506 via an application server 504. As discussed in the example above a billing server at 508 can optionally log the subscriber ad content selection and an Ad Campaign Manager at 510 can be used to deliver the subscriber selected ad content (or content in accordance with a selected subscriber preference) to the STB via an ad delivery system 512. The ad delivery system can include a unicast transmission system, but can utilize other transmission system where specific ad content can be inserted or splice into a video stream for delivery to the STB at 514.

From an STB, a subscriber can be presented with a screen or GUI that allows them to choose specific advertising content from an Advertisement Content Storage via an integrated IPTV Application Server. Once the subscriber has selected the advertisement content that piques his or her interests, this information will then be stored on the Ad Delivery Server using for example the STB's GUID (Globally Unique Identifier). Then once the broadcasted content calls for an advertisement to be inserted, the specific advertisement content that the subscriber specified will be spliced into the viewed video stream. If the subscriber does not select any content, then default ad insertion policies can be applied. The other service providers simply broadcast advertising content during specific time slots to all viewers.

FIG. 6 depicts an illustrative method 600 that operates in portions of the communication systems of FIG. 1. Method 600 can begin with step 602 in which the method at 602 presents a graphical user interface (GUI) enabling subscriber selectable advertisements for delivery of the subscriber selectable advertisements to a set top box (STB). At 604, the method 600 can present filters for targeted ad delivery based on one or more of demographics, geographic location, purchased products, or purchased services. At 606, the system (or subscriber) can select ads from an ad catalog server (based on subscriber selected preferences or subscriber selections) and transmit the STB's Globally Unique Identifier (GUID) to a billing server. At 608, such selection can initiate storage of the subscriber selectable advertisements at a remote ad delivery server, where the storage of the subscriber selectable advertisement can be done using a STB's GUID. At 610, the method can present the present the subscriber selectable advertisement, optionally using a unicast stream server. In one embodiment, the method at 612 can receive a unicast of a subscriber selectable advertisement selected by an ad campaign manager and play the subscriber selectable advertisement selected by the ad campaign manager when a que tone is delivered in a broadcast stream. Transmission of the ad can involve splicing the subscriber selectable ad at 614 into a digital video stream before the presentation (610). In yet another option, the method at 616 can collect EPG information or channel subscription information from an IPTV network to provide further automated targeted ad delivery. It should be understood that the order or inclusion of the steps should not be implied from the specific order described herein.

Upon reviewing the aforementioned embodiments, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below. For example, such a system and method can entail in a particular embodiment an STB or server which can ultimately insert ads in a similar fashion as discussed above where the IPTV system is further coupled to a wireless network and remote devices as illustrated in FIG. 1. Such remote device can also be treated as an STB in the context of the embodiments herein.

Other suitable modifications can be applied to the present disclosure without departing from the scope of the claims below. Accordingly, the reader is directed to the claims section for a fuller understanding of the breadth and scope of the present disclosure.
